Why The Mammoth Extinction Is More Mysterious Than We Thought

Four thousand years ago, while the pyramids at Giza stood finished and cities rose across Mesopotamia, woolly mammoths were still walking on an island in the Arctic Ocean. Then they vanished — and after decades of research, nobody can say why. This documentary traces the collapse of Ice Age megafauna across two continents: the mammoth steppe and the ecosystem it supported, the thirty-seven genera of large mammals lost from North America, the overkill hypothesis and the archaeological evidence that strains it, the competing climate models, and the last surviving mammoth population on Wrangel Island — whose genomes and bone chemistry have made their final disappearance more mysterious, not less.

Where researchers disagree, this film says so. Where the evidence is unresolved, it stays unresolved.
